JOSEPH AUTH AND HENRY KETTLER, OF COVINGTON, KENTUCKY.

WAGON-BRAKE.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed. June 29, 1809. Serial No. 505,054.

To all whom tt may concern:

Be it known that we, JOSEPH. AUTH and HENRY KETTLER, citizens of theUnited States, residing at Covington, in the county of Kenton and Stateof Kentucky, have invented certain new and useful Improvements inlVagon-Brakes; and we do hereby declare the following to be a full,clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marks thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in brakes forvehicle wheels and comprises a simple and eficient device having variousdetails of construction, conbinations and arrangements of parts whichwill be hereinafter fully described and then specifically defined in theappended claims.

-We illustrate our invention in the accompanying drawings, in whichFigure l is a side elevation of a wagon showing our improved brake asapplied thereto. Fig. 2 is a sectional view showing parts in elevation.Fig. 3 is a cross sectional view through two of the wheels, parts beingshown in elevation. Fig. 4 is an enlarged sectional view showing thebrake shoes thrown at their farthest limits from each other, and Fig. 5is a similar view showing the brakes set.

Reference now being had to the details of the drawings by characters, Adesignates the rear aXle of a vehicle upon the contracted end of whichis journaled a Wheel B. Fixed to said aXle are the friction disks C, Cand D, D are disks which are fastened to the hubs E, E of the wheels andare held together by means of bolts F, the spokes of the wheels beingclamped intermediate said disks C and D. Fastened to the rear axle arethe angle bars G, each of which has fastened thereto a plate H. Friction shoes, designated by letters I and I', are pivotally mountedupon the pins K which are mounted between the two links H and H' and areconcaved and adapted to conform to and hear against the circumference ofthe friction disk C when the brakes are applied. One of said brake shoeshas an outwardly inclined surface O and the other shoe of each pair isprovided with an oppositely inclined edge Q and a spring J is interposedbetween the parallel portions of the brake shoes and adapted to normallyhold the same apart.

Journaled in suitable bearings in the bolster L is a rock shaft Nprojecting from which is a bar L to which a chain or rod N' is connectedwhich, in Figs. l and 2, is shown as attached to a foot lever L formingconvenient means whereby the brake may be applied. Said rock shaft N hasa plate R fixed thereto and adapted to rock with the shaft and a secondplate R' is held to the plate R by means of bolts R and caused to rocktherewith. Mounted upon each of the bolts R is a roller R one of whichis adapted to hear against the inclined edge O upon a brake shoe I whilethe other roller is adapted to bear against an inclined edge Q upon thebrake shoe I', thus causing the two brake shoes, as the shaft L isrocked, to move toward and frictionally engage the circumference of thedisk C. When the pressure is relieved from the brake shoes, the springwill return the brake shoes to their normal positions out of engagementwith the disk.

From the foregoing it will be noted that, by the provision of a brakeand shoes embodying the features of our invention, a simple andefiicient mechanism is afiorded whereby, with a slight pressure appliedto the operating lever, the two brake shoes may' be thrown into contactwith the friction disk with such force as to hold the wheel from turningand, when pressure is relieved from the brake shoes, the Springs willthrow the same out of engagement with the friction disk.

While we have shown our brake as applied to a particular form of runninggear, it will be understood that we donot restrict ourselves to anyparticular detailed manner of attaching the brake and it will beunderstood that the same will be applied to various forns of vehiclewheels without in any way departing from the spirit of the invention.

hat we claim to be new is 1. A brake for vehicle wheels comprising, incombination with a running gear and Vehicle wheel, a friction diskrotating therewith, friction shoes mounted upon the running gear of avehicle, said shoes having inclined edges which are parallel with eachother, a rock shaft, bars secured thereto, rollers journaled betweensaid bars and adapted to bear one against each inclined edge of the shoeand adapted to move the shoes toward each other, and a spring forreturning the shoes to their nornal positions,

2. A brake for Vehicle wheels conprising, in combination with a runninggear and ve: hicle wheel, a friction disk rotatingv with the latter,friction shoes piv'oted together and having their ends which extendupwardly provided each with an inclined edge which are parallel to eachother, a rock shaft journaled in, suitable bearings in the running gear,bars secnred to said rock shaft, rollers journaled intermediate saidbars and adapted to be thrown in contact with one of said inclined edgesas the shaft is rocked in one direction, and a spring for returning theshoes to their nornial positions.

3. A brake for Vehicle wheeis conprising, in combination with a runninggear and ve hicle Wheel, a friction disk rotating therewith, frictionbrake shoes, links pivotally Connecting said brake shoes, the upper endsof said brake shoes having their outer edges inclined, a rock shaftournaled in the running gear, plates fixed to rock with said shaf-t,rollers journaled between the plates and adapted to engage each of saidinclined edges, and means for rocking the shaft.

4. A brake for Vehicle wheels conprising,

in combination with a running gear and Ve-,

hicle Wheel, a friction disk rotating therewith, angled bars fastened tothe axle of the running gear, links fastened to said bars,

brake shoes pivotally connected to said links,

the free ends of said brake shoes having their outer edges inclined, arock shaft journaled in the running gear, plates secured to said rockshaft, rollers journaled internediate said plates and adapted to bearagainst said inclined edges, and means for rocking said shaft.

In testimony whereof we hereunto afix our signatures in the presence oftwo witnesses.
